Calfee’s Public Utility, Energy, and Telecommunications Litigation practice group is exclusively focused on the unique issues faced by public utilities, their customers, and market competitors. Calfee attorneys have been involved in many of the significant regulatory cases in Ohio, Indiana, Illinois, and FERC, and have litigated utility-related claims in state and federal courts in multiple states. There is a reason our clients have trusted us with their multi-billion-dollar litigation.

Calfee’s Public Utility, Energy, and Telecommunications Litigation group recognizes that public utility litigation is unique. Public utility litigation involves all of the issues of traditional litigation, demanding counsel with experience in litigating major cases. However, utility litigation also involves a host of interactions with governmental authorities, a significant factor that is not present in traditional litigation. 

Utilities must also be conscious of the potential impact that regulatory litigation may have on Commission staff, the Power Siting Board, local governments, and potential legislative involvement. Calfee’s knowledge and expertise in this area allow us to be a full-service provider, structured and operated in a manner that recognizes that utility issues significantly impact the public and, therefore, have fundamental governmental implications.

We have represented one of the nation’s largest electric utilities, municipal electric utilities, municipal water and sewer utilities, cooperatives, natural gas distribution companies, intrastate natural gas pipelines, local telephone and cellular telecommunications carriers, brokers, and industrial customers.

Our attorneys operate in concert with the firm’s Government Relations and Legislation group. This team approach allows us to achieve timely results that meet our clients’ immediate, strategic, and long-term needs. We recognize that our clients’ issues are best served when regulators, customer advocates, elected officials, and their staff are fully informed. Accordingly, we make our clients’ views and concerns known to and understood by regulatory and elected decision-makers at all levels through both formal advocacy and lobbying efforts.

We use our broad governmental, financial, corporate, litigation, and public law experience to provide innovative, business-oriented solutions to the complex issues that confront our clients.
